There existed the Patiala and the East Punjab Union (PEPSU) alongwith State of Punjab which also had its own High Court known as a PEPSU High Court. The State of PEPSU was merged in the State of Punjab by the States Reorganization Act, 1956 and accordingly the Punjab High Court assumed jurisdiction over the territories which were under the PEPSU High Court.
